Eel scale. Light micrograph of a scale from the skin of an eel (Anguilla anguilla). The scales are just under the skin and form a protective skeleton. Each scale plate consists of a lower fibrous plate and an upper clear plate of dentine. Dentine is added to the edge of the plate each year. In the summer the plate grows faster (thick ring) than in the winter (thin ring), so each year's growth is demarcated. On this scale, there are five concentric growth rings, which means the eel is approximately five years old. Magnification x103 when printed at 10 centimetres across.
